First, you will need to build the binary in release mode. Debug builds are significantly slower:

```bash
cargo build --features unix --release
cargo build --features unix --profile profiling
```

```bash
# Three-way comparison benchmark
hyperfine \
--warmup 3 \
"/usr/bin/ls -R ." \
"./target/release/coreutils.prev ls -R ." \
"./target/release/coreutils ls -R ."
"./target/profiling/coreutils.prev ls -R ." \
"./target/profiling/coreutils ls -R ."

# can be simplified with:
hyperfine \
--warmup 3 \
-L ls /usr/bin/ls,"./target/release/coreutils.prev ls","./target/release/coreutils ls" \
-L ls /usr/bin/ls,"./target/profiling/coreutils.prev ls","./target/profiling/coreutils ls" \
